TB and Air Chage Pipe what options are there?
I searched around and all I can find is BBK and pauls high performance for throttle bodies and AFE and pauls high performance for the air charge pipe. Are there any other brands or companies I should be looking at?

That's all I've seen, you can always port you own TB...I've polished and ported a few.
DISCLAIMER: They are easy to mess-up if you get carried away. I've been thinking about pulling mine and doing it...might do it tonight. There's not much to be gained until you start to pull more air. I would guess gains with a tune might be about 8whp.

mmm, depends on the material available. Stock 68mm I think...BBK is 73mm...I'm sure you could, but dealing with TB's sometimes less is more. There's a happy medium...and 73mm is pretty upsized on a stock configuration...moving on up to being good to 500hp on a complete whim guess. I think 75mm, would be over kill unless you'll be doing ATP's +2 turbos, haha....might be overkill for that.
My personal experience is that the slope is equally, if not more, important than the actual diameter. I am still on the fence, my plan is to "polish" more than port...the stock TB has some rough casting area in the beginning.

Just depends on how far you want to take it. I pulled the stock TB and polished it the stock casting is pretty rough. I might have opened it up 1-2mm...but I was mainly trying to smooth it out. One thing people overlook is that adding a larger TB normally loses mileage...Everytime I've bought or ported my own, I've lost mileage.
What I noticed afterwards: A drop of about 200RPM...idling at 600-700 rpms (oops). More turbo noise and my exhaust sounds deeper.
Another oddity---AFR quickly richens to 13.89 and then back 14.6-.7 on partial throttle. Prior I've always noticed it leaned out to ~15.2. So it changed something and I'm assuming the computer is trying to adjust.
As far as performance...pfft, there's no gain to be felt or seen via Tq Pro. All my numbers look as they did before minus the AFR's.
